Internet Protocol Security (IPSec) provides data protection during network communication. Which of the following tasks can be performed by IPSec? Each correct answer represents a complete solution…
The correct answer is A. Ensures the integrity of the IP data. B. Authenticates the sender of IP data. C. Encrypts all data for full confidentiality. IPSec provides data integrity, sender authentication, and confidentiality through its AH and ESP protocols, but it does not have a feature to display originating IP addresses.

Why each option
IPSec provides data integrity, sender authentication, and confidentiality through its AH and ESP protocols, but it does not have a feature to display originating IP addresses.
IPSec uses the Authentication Header (AH) protocol to compute a cryptographic hash over the IP packet, allowing the receiver to detect any modification in transit and thereby ensuring data integrity.
IPSec authenticates the identity of communicating parties using digital certificates or pre-shared keys, verifying that packets originate from a trusted and legitimate sender.
IPSec's Encapsulating Security Payload (ESP) protocol encrypts the packet payload using symmetric encryption algorithms such as AES, providing full confidentiality for data in transit.
Displaying originating IP addresses is a basic function of IP routing visible in standard packet headers and is not a security service offered by IPSec; in tunnel mode, IPSec can actually obscure original addresses.
